Figure 1 is a schematic structural diagram of the assembly platform. In the figure, the pressing device is located in the middle of the operating surface 3 of the assembly platform. The head of the pressing device protrudes from the hollow area of the operating table 3 . Figures 2 and 3 are schematic diagrams of the assembly platform in an unpressed state and a pressed state. In the two figures, the position of the pressing device of the assembly platform is enlarged. In Figure 2, it can be seen that most of the area of the pressing device in the recovery state 14 is located inside the assembly platform. In Figure 3, the pressing device rises upward to facilitate the pressing. The fasteners are pressed together. The picture on the left does not show the pressed part. Area I shows the pressing device after removing the pressed part. The space left between the pressure arm and the operating table 3. In contrast, the pressed part shown in the right figure is the stage 4, and the pressing arm of the pressing device is pressed on the top of the edge of the stage 4.

Figures 4 to 6 are schematic views of the pressing device in different directions. There are two pressing parts 1 shown in the figure, and they are symmetrically distributed. Figure 7 shows the different states of the pressing device during operation (all views in the figure are rotated 90° clockwise). Driven by the driver 22, the two pressing parts 1 will move along the same motion plane.

As shown in FIGS. 1 to 7 , the pressing device in this embodiment includes a linear driving mechanism 2 and a pressing part 1 that are connected to each other. The linear drive mechanism 2 has a moving part 21 that is operable to reciprocate in the driving direction. In contrast, the pressing part 1 has a driven part 11 and a swinging part 12. The driven part 11 has an oppositely arranged driving end 111 and a pressing end 112 and a connection area between the driving end 111 and the pressing end 112. 113. The swinging member 12 has a connecting end 122 spaced apart from the swinging center 121. The connecting end 122 and the connecting area 113 form a first rotating pair A1. The driving end 111 of the pressing part 1 forms a second rotating pair A2 with the moving member 21 respectively. . Driven by the linear drive mechanism 2, the pressing part 1 has a pressing state 13 and a recovery state 14 during its movement stroke. When the pressing part 1 is in the pressed state 13, the moving part 21 pushes the driven part 11 to turn sideways in the driving direction. When the pressing part 1 is in the retracting state 14, the moving part 21 pulls the driven part 11 to retract in the driving direction.

In this embodiment, the moving part 21 is used to provide driving force to the pressing part 1, and the swinging part 12 is used to limit and guide the movement trajectory of the follower 11. For this reason, the position of the swinging center of the swinging part 12 is in a relatively fixed state. Therefore, under the joint action of the moving part 21 and the swinging part 12, the driven part 11 can perform two actions of rotation and up-and-down movement at the same time. Figure 7 shows a movement trajectory after the above two actions are combined. The direction B shown by the double-headed arrow in the figure is the driving direction in this embodiment. That is, the direction of movement of the linear drive mechanism 2 . The left picture in Figure 7 shows the pressing device in the recovery state 14. In this state, the driven member 11 moves downward in the driving direction, so that the arrangement direction of the driven member 11 is consistent or substantially consistent with the driving direction. The middle picture in Figure 7 shows the process of the pressing device opening upward. state, at this time, as the driven member 11 flips toward the outside, the driven member 11 also moves upward simultaneously. The right picture in Figure 7 shows the fully opened state, that is, the pressed state 13. At this time, the follower 11 has been fully opened and pressed onto the pressed member. The figure also shows the operation table 3. With reference to the operation table 3, it can be seen that from the recovery state 14 to the pressing state 13, the follower 11 not only flips to both sides, but also rises upward at the same time, and finally its The bottom and the operating table 3 create an empty area I.

The pressing device of the embodiment of the present invention uses the linear drive mechanism 2 to drive the pressing part 1, and further uses the mutual cooperation of the first rotating pair A1, the second rotating pair A2 and the swinging member 12 to adjust the linear motion of the moving member 21. This movement translates into a movement in which the output element 11 can be tilted sideways and retracted in the drive direction. Therefore, the pressing part 1 controlled by the moving part 21 can pressurize the pressed part, thereby improving work efficiency. At the same time, the pressing part 1 can be retracted after the pressing operation is completed, which reduces space occupation.

Preferably, there are multiple pressing parts 1 , and each of the driving ends 111 on the multiple pressing parts 1 forms a plurality of second rotation pairs A2 with different positions of the moving part 21 . As a result, the moving part 21 drives multiple pressing parts 1 at the same time to achieve pressing action on multiple pressed parts at the same time, further improving work efficiency. At the same time, it can also ensure the consistency of the pressing force on each pressed part. On the other hand, a single linear drive mechanism can be used to drive the movement of multiple pressing parts, which reduces the occupation of the internal space of the assembly platform.

Alternatively, the pressed part may be a workpiece to be assembled, a workpiece to be inspected, or a stage 4 for carrying the workpiece, etc. Different pressed parts have different sizes, so the driven part 11, the swinging part 12 and the driving stroke can be adjusted adaptively. For example, when the thickness and width of the workpiece to be assembled are large, the distance between the pressing end 112 and the connecting area 113, the distance between the connecting end 122 and the swing center 121 can be increased, and the driving stroke can be adjusted adaptively. In this way, stable pressing of the above-mentioned workpieces to be assembled is achieved.

In other embodiments, the connection between the swinging member 12 and the driven member 11 is set to a fixed connection, that is, a fixed connection is used to replace the first rotating pair A1 in the above embodiment. In this connection mode, the swing member 12 and the driven member 11 are relatively fixed and rotate together along the swing center 121 . Therefore, it is no longer possible to drive the driving end 111 through a straight path. Therefore, the connection method between the linear driving mechanism 2 and the driving end 111 needs to be changed accordingly. For example, the moving part 21 of the linear driving mechanism 2 is provided with a device that can move horizontally and is connected to the driving end. 111 to compensate for the position change of the driving end 111 in the horizontal direction in this embodiment.

In some embodiments, as shown in Figures 1 to 7, the rotation axis of the first rotating pair A1 is the first hinge point A11, and the rotation axis of the second rotating pair A2 is the second hinge point A21. The swing center of the member 12 is the third hinge point A31. There is a first predetermined distance between the first hinge point A11 and the second hinge point A21, and there is a second predetermined distance between the first hinge point A11 and the third hinge point A31. The driving stroke of the moving member 21 is configured to be no less than the sum of the first predetermined distance and the second predetermined distance. The left figure in FIG. 7 shows an outline of the swinging member 12 and the driven member 11 formed by a dotted line. The hinge point A11′ of the dotted line outline is the position rotated 90° counterclockwise from the first hinge point A11. The hinge point A11′ can also be understood as the first hinge point A11 in the figure on the right.

As can be seen from FIG. 7 , the actual stroke of the linear drive mechanism 2 is the movement distance of the second hinge point A21 , that is, from the second hinge point A21 in the figure to the hinge point A21 ′. This position distance is actually the sum of the distances from the A11′ hinge point to the third hinge point A31, and then from the third hinge point A31 (equivalent to the first hinge point A11) to the second hinge point A21. In other words, the distance is the sum of the first predetermined distance and the second predetermined distance.

In this embodiment, in order to meet the demand for the movement stroke of the pressing part 1, the driving stroke of the linear driving mechanism 2 is configured to be greater than or equal to the sum of the first predetermined distance and the second predetermined distance. At the same time, the first predetermined distance is related to the thickness of the pressed member. When the thickness is thicker, the first predetermined distance can also be increased accordingly. In contrast, the second predetermined distance is equal to the width or length of the pressed member. Relatedly, when the distance between the driving end 111 and the pressing end 112 is desired to be fixed, reducing the second predetermined distance can increase the extension length of the pressing end 112, that is, more areas of the pressed part can be pressed. Or the above effect can also be achieved by directly increasing the distance between the pressing end 112 and the first hinge point A11.

Further, the driving stroke includes a first dead center and a second dead center, and the first dead center and the second dead center are respectively located at both ends of the driving stroke. The first dead point corresponds to the pressing state 13, and the second dead center corresponds to the recovery state 14. When the pressing part 1 is in the pressing state 13, the line connecting the first hinge point A11 and the second hinge point A21 is perpendicular to the line connecting the first hinge point A11 and the third hinge point A31. Region II and region III in FIG. 7 respectively show that the piston 223 in the driver 22 is located at the second dead center and the first dead center. The piston 223 is connected to the output shaft 221 .

Optionally, the driver 22 in this embodiment may be a driving device such as a linear motor or a cylinder. Taking the cylinder used in pneumatic transmission as an example, the stroke of the piston 223 is configured to be the same as the sum of the first predetermined distance and the second predetermined distance. At the same time, when the piston is in region II, the pressing part 1 is in the recovery state 14, and when the piston 223 is in region III, the pressing part 1 is in the pressing state 13. At this time, the moving direction of the piston 223 can be adjusted by supplying air to the two chambers of the cylinder, while also ensuring that the follower 11 does not move too much. For example, in the pressing state 13, the piston 223 is limited by the top wall of the cylinder chamber, so that the follower 11 does not exert excessive pressure on the pressed part, causing damage to the pressed part.

In some embodiments, as shown in FIGS. 1 to 7 , the linear drive mechanism 2 also has a driver 22 , and the driver 22 includes an output shaft 221 . The moving part includes a first connecting block 211 and a plurality of connecting columns 212 . The plurality of connecting columns 212 correspond to the plurality of pressing parts 1 one-to-one. One end of the connecting column 212 and the driving end 111 form the second rotating pair A2, and the first connecting block 211 is fixedly connected to the other end of the connecting column 212 and the output shaft 221.

This embodiment uses the cooperation of the connecting column 212 and the first connecting block 211 to connect the driver 22 and the driven member 11, and uses the connecting column 212 to configure the entire pressing device into an upper and lower structure (as shown in Figure 4 (shown in the figure), the driver 22 is arranged below the plurality of pressing parts 1, so that the distance between the plurality of pressing parts 1 in the horizontal direction can be closer, simplifying the overall structure of the pressing device.

In some embodiments, as shown in FIGS. 1 to 7 , the pressing part 1 further includes a fixing member 15 . The fixing member 15 includes a second connecting block 151 and a fixing block 152 . One end of the second connecting block 151 is connected to the fixing block 152 Fixedly connected, the other end of the second connecting block 151 and the swing center position of the swing member 12 form a third rotating pair A3. The plurality of connecting posts 212 are arranged symmetrically with respect to the output shaft 221 , and the fixing member 15 is located on the side of the connecting posts 212 away from the output shaft 221 . Figure 7 shows that there are two pressing parts. The swinging part and the second connecting block 151 form the third rotating pair A3. A plurality of driven parts 11 are located inside the fixed part 15. This way, the connecting column 212 drives the Below, the two followers 11 can be extended outward or retracted inward.

Further, the side of the follower 11 facing the second connecting block 151 includes a pressing surface 114. The end of the second connecting block 151 has an escape surface 153 corresponding to the pressing surface 114. The pressing surface 114 and the escape surface 153 Have intervals.

In this embodiment, the pressing surface 114 is used to exert pressure on the pressed parts. Therefore, when the driven member 11 rotates around the second connecting block 151, the escape surface 153 of the second connecting block 151 and the pressing surface 114 need to be maintained. A certain distance is provided to prevent collision between the pressing surface 114 and the second connecting block 151 . FIG. 4 shows a total of three locations of the escape surfaces 153 , and these locations are close to the second connecting block 151 when the driven member 11 rotates.

Specifically, the number of pressing parts 1 is two, and in the pressing state 13 of the followers 11 of the two pressing parts 1, the pressing ends 112 face opposite directions. When the pressing device in this embodiment is used, two pressed parts can be arranged at intervals on both sides of the pressing device, that is, the pressing device is placed in the middle of the two pressed parts. This avoids the two pressed parts from interfering with each other and saves space occupation.

Preferably, as shown in Figures 4 to 6, the driven member 11 and the swinging member 12 in the above embodiment can be configured as a pressing arm and a swing link respectively, wherein each pressing part 1 is configured with two swing links. , one end of the two swing links is clamped on both sides of the connection area 113 to form two first rotating pairs A1. another The ends are clamped on both sides of the top of the second connecting block 151 to form two third rotating pairs A3. The head of the pressing arm is the pressing end 112, and the tail is a guide groove. The guide side wall of the guide groove extends along the motion plane of the follower 11. The head of the connecting column 212 that cooperates with the guide groove is configured as a duckbill structure, and the duckbill structure penetrates into the guide groove to form the second rotating pair A2. The above-mentioned first rotating pair A1, second rotating pair A2 and third rotating pair A3 are all provided with movable holes in their rotation centers, and movable pins are arranged inside them. The rotational connection of the pressure arm, swing link and connecting column is realized through the cooperation of the movable hole and the movable pin. As a result, the weight of the holding device is reduced and the appearance of the parts is simplified.

The pressing device in the above embodiment can be applied to the assembly platform to achieve clamping of components on the assembly platform. In an optional implementation, as shown in Figures 1-7, the assembly platform includes the pressing device and the operating table 3 in the above embodiment. Optionally, the pressing device is arranged adjacent to the operating surface 3 , that is, it is arranged outside the operating surface 3 and immediately adjacent to the operating surface 3 . At the same time, after the follower 11 is turned over, the pressing end 112 can face the operating table 3 . In order to apply a pressing force to the fastened parts on the operating table 3.

The assembly platform of the embodiment of the present invention uses the linear drive mechanism 2 to drive the pressing part 1, and further controls the linear motion of the moving part 21 through the mutual cooperation of the first rotating pair A1, the second rotating pair A2 and the swinging member 12. This translates into a movement in which the driven element 11 can be turned sideways and retracted in the driving direction. Therefore, the pressing part 1 controlled by the moving part 21 can pressurize the pressed part, thereby improving work efficiency. At the same time, the pressing part 1 can be retracted after the pressing operation is completed, which reduces space occupation.

In some embodiments, as shown in FIGS. 1 to 7 , the assembly platform further includes a carrier 4 . The operating table 3 includes a window 31 and a plurality of positioning pins 32, and the pressing part 1 of the pressing device is located at the position of the window 31. The carrier 4 is detachably mounted on the operating table 3 through positioning pins 32 and is arranged adjacent to the window 31 . The follower 11 of the pressing part 1 is operably pressed on the top of the carrier 4 . This embodiment is provided on the operating table 3 There is a window 31 for extending the pressing part 1, and part of the pressing device is located in the window 31. When the stage 4 needs to be fixed, the driver 22 will completely push the driven member 11 out of the window 31, and then press it. On the platform 4.

Preferably, the number of the stage 4 and the pressing parts 1 is correspondingly set to multiple, and the stage 4 is arranged around the window 31 , so that multiple pressing parts 1 can simultaneously press multiple stages 4 Press separately to improve work efficiency.

Specifically, FIG. 5 shows a window 31 structure. The window 31 in the figure is a rectangular frame. The fixing block 152 on the pressing part 1 is generally a rectangular structure and is fixed to the bottom of the operating table 3 . The second connecting block 151 is connected to the middle area of the fixing block 152 and is located in the rectangular frame. The fixing block 152 is set up on both sides of the rectangular frame in the length direction of the rectangular structure. Therefore, the interconnection between the fixing block 152 and the three surfaces of the operating table facilitates quick disassembly and assembly of the two, and at the same time reduces the occupation of the internal space of the assembly platform.
